More specifically, the system is capable of providing a calculator screen (UI) for a question requiring a calculator function and removing the calculator screen when the calculator function is not necessary, and therefore, a learner does not need to have a calculator. Moreover, an examiner is able to choose whether to use the calculator function, and the learner is able to store calculator use information, including whether to use the calculator, how long the calculator is used, and calculation procedures, in a service device, and therefore, the learner and the examiner are able to share the information and to use solution procedures for learning. |
